Answer:
Step-by-step explanation:
Consider the coordinates of B(x,y).
as M is midpoint of AB so,
2a = (x+a)/2
4a = x + a
x = 4a - a
x = 3a
Now for we will find y
2 = (7+y)/2
4 = 7 + y
y = 4 - 7
y = -3
Hence coordinates of B are ( 2a, -3 )
Answer:
$21.51
Step-by-step explanation:
$71.70-70%=$21.51
Answer:
Step-by-step explanation:
-15.4b + 13 = 9b-41.9
-15.4b-9b = -41.9 - 13
-24.4b= -54.9
divide both side by -24.4
-24.4b/-24.4 = -54.9/-24.4
minus divide by (-)
b= 2.25
Answer:
(4^3)3 and 4^3 • 4^3 = 192 and 4096 = No
(3^4)^4 and 3^8 • 3^8 = 43046721 and 43046721 = Yes
6^4 • 3^4 and 18^8 = 104976 and 11019960576 = No
4^3 • 5^3 and 2^0 = 8000 and 1 = No
